IMPROVEMENT IN SOLDERlNG-FURNACES.

Specification forming part of Letters Patent No. 126,590, dated May 7, 1872.

To all whom it may concern:

Be it known that I, GEORGE A. TOWNSEND, of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in a Fire-Pot or Soldering-Furnace for heating coppers for tin-plate working, roofing, and for other purposes; and the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing making a part of this specification, in which- Figure 1 represents a side view of my improved soldering-furnace. Fig. 2 is a sectional view through the same, showing the coal-cylinder, draught-holes and damper, fire-place and openings to insert the soldering-irons or coppers, ash-pit, and base. 7 Fig. 3 is aview of the conical coal-receiver and fire or coal-burning space, removed from the vertical cylinder or outer case.

My invention relates to fire-pots for heating soldering-irons and it consists in the construction of the conical coal-receiver, fire-place, and damper, so arranged and combined with the outside cylinder that it can be turned in either direction to close up the openings in front, and can be all easily taken out for cleaning.

To enable others to make and use my improvements, I will describe them more fully,

referring to the drawing and the letters marked thereon.

The outside cylinder A, base B, hearth G, and bail D are constructed similar to the ordinary fire-pots most in use, to which I put the addition of the curved draught-pipe G near the top in the rear of the hearth O, and openings 0 c for giving the necessary draught to ignite the coal. Into the cylinderA is fitted a conical sheet-metal coal-receiver, E, which fits close- 1y at the top, and extending down about twothirds the length of the outside cylinder, taperin g inward to about two-thirds the diameter of the opening in the top, which has a lid or cover,

F, to close it tight, to prevent the air from passing up throughthe coal when in use. To the lower end of the coal-receiver E is fitted and secured the fireplace or cylinder H, which may be made of cast-iron, clay, or other suitable substance, the right size to fit in the cylinder A, and is provided with crowning openings 6 e on one side to correspond with the openings 0 c in the outer cylinder above the hearth U, in which the solderin g-irons f are placed for heating, the bottom below being supplied with a coating of sand or ashes to prevent heating. The conical offset I, between the fire-box H and the coalreceiver E, is perforated with a series of holes, '6 *5, over which is a corresponding movable ring-plate, J, to form a damper to close up the holes 13 i and cut off the draught or regulate it, as may be. desired, the same being operated by inserting the pin j into the socket of the damper through the narrow slit in the side of the cylinder A. The top of the coal-receiver E is provided with ears or handles h h, whereby it can be turned in either direction sufficiently to close the openings 0 c in front of the cylinder A, so as to eflectually shut in all of the ashes, fire, and coal, so that no sparks can be blown out nor any of the contents scattered when it is left or being carried about for use. The interior can all be lifted out by the ears h h for cleaning.

What I claim as my invention, and desire to secure by Letters Patent, is

The detachable conical coal-receiver E, fire-.

place H, and damper J, in combination with the outer cylinder A, all constructed and arranged substantially as herein set forth.

In testimony whereof I hereunto subscribe my name.

GEORGE A. TOWNSEND.
